A C3-symmetrical tripodal acylhydrazone organogelator for the selective recognition of cyanide ions in the gel and solution phases: practical applications in food samples

Abstract

The method of formation of low-molecular-weight organogelators via modifications in the substituents has been demonstrated. The organogelator formed can selectively sense cyanide ions in the gel and solution phases. Interaction of cyanide with acylhydrazone was noticeably visible to the “naked eye” and was proved using ¹H NMR titrations. Notably, the ligand has been successfully explored for the recognition of cyanide ions in food samples. Additionally, low-cost cotton swabs coated with the organogelator showed rapid, on-site recognition of cyanide ions. The structure–property relationship discovered in the given study provides insight into the development of novel, cost-effective multifunctional materials.
